That wasn't 100 percent real: "I was jokingly being dramatic about getting one," she wrote on her blog today, adding, "They can be from stress!" (Aw, Kenny.) But then she made one thing clear: Her fear of adulthood is no joke.

The gray hair and aging, "it honestly does kind of freak me out," she wrote. "When I turned 20, I was scared, as crazy as that sounds. I just didn't feel ready to be out of my teens, yet—I didn't want to be in my twenties. I feel like your twenties are when you actually have to grow up and be an adult, which is scary!" Or, as Kylie Jenner sagely put it, it's "the year of just realizing stuff," plus nine more years of just realizing stuff:

But Jenner relives her youth deliberately to combat this natural process. "I've always tried to keep any bit of my 'kid life' that I can. It's so important for me to be silly and goof off because I think that's what keeps people feeling young—whether they're 20 or 60."
